RAIN WATER PIPE Application filed September 21, 1928 Serial No. 307,495,and in British IndiaApril 30, 1928.

This invention relates to rainwater pipes andhas for its object toprovide a rain water 1 pipe .Whichcan be secured in position morecheaply and in a better manner mechanically than rain water pipes-aren'ow fixed Another object is to provide a rain water pipe which needs noseparate brackets, collars or fixing bands requiringnails on eitherside, and a still further object is to avoid the use of pairs of castperforated lugs or ears on a rain water pipe through which spikes is abrittle projection and there is a great;

danger that in driving'a spike through the hole therein and into a wallthe hammer may i hit and'break off the lug. Further owing to two lugs atleast being needed, one on either 'side of the rain Water pipe, andowing to the difficulty of driving spikes in theexact' position desiredin a'masonry wall it often" occursthat thespikes go out of position indriving or become crooked with the result that aside strainand'eccentricpull is thrown on the cast iron lugs which they are quite "unfitte'd toresist, being of thin cast iron.

' Sometimes rain waterpipes 'are fixed by t usingsecuringbandswhich areplaced around the pipe and secured by driving a spike there-through oneither side of the pipe.

Such bands hold the pipe in place but usual- 1y do not support thedifferent length which accordingly nest'into-each other, with the resultthat the lowest pipe carries 'the weight of all the other pipes thereon,which weight may be transferred thereto unevenly owing to point contact.

1 In either of these caseseach length of. the

pipe nee'dsat least two spikes to hold it, and these spikes may or maynot be efiicient in helping to carry the weightiof the pipe.

f r Y r of the pipe or spout length is a part which is V length.

I Now according tothe present invention a single spike or the like maybe used for supporting each length of pipe. This method accordinglyreduces the number of spikes or the like to half, thus reducing costandlabour. a

The spike is moreover driven on the centre lines of the rain water pipeand hence tends to carry the pipe suspended therefrom in the mostefficient manner. There can thus projections are not so likely to bedamaged or broken off as the large ears or lugs on ordinary castironpipes.

Further objects and features will be apparent from the followingdescription.

The invention consists of an improved rainwater pipe ofthe spigot andsocket type adapted to be suspended from or supported by a single simplenail, spike hold-fast or the like supporting means, characterized bythis that the socket which is'intended, when 1 in use,to be at the upperend of the'pipe length is provided with an aperture or slot in the wallsthereof for the introduction therein of or attachment therefrom to thesupporting means, and these walls give sufficient clearance between themand the spigot end of the next length'of pipe which is to be introducedinto the said socket end to allow of the pipe being thusjsupported andthereafter the next length of piping'thereabove bef from said socketend, characterized by this that the perforated, slotted or aperturedpart kinked out or off-set from the socket part by such amount that thehead of the nail, spike or other supporting means intended to be driveninto the wall to support the pipe shall not prevent the end of the nextsection of the pipe above from being fitted into the section alreadyerected and fixed.

The pipe may be one in which the hole, slot or aperture is made adjacentto the top of the pipe and an intermediate attaching means, for examplea flexible piece of wire, or a metal loop or hook,,or a chain, is engaged in said hole, slot or aperture and is adapted to be hooked over orto engage the supporting nail, spike or the like supporting means tosupport the pipe or spout length. Alternativelythe hole, slot oraperture made in the socket of the pipe may be adapted to supporttherpipe directly from a supporting means with a flattened head.

The pipe according to this invention may have an apertured and slottedsocket and in addition afoot or staying surface, for examplea block,projection or projections, with a flat portion thereon adapted to engagethe wall towhich the pipe or spout is to be fixed for the purposeofsteadying the pipe against the wall, enabling it to hang vertically fromits nail or the like and to prevent, by frictional contact with the,wall, any tendency to-sidc movement.

T he; pipe is one which alternatively is adapted to be supported byhaving an aperture therein enabling it to be wired to a sup portingnail, or-the like.

The invention includes a pipe having in combination a socket part at itsupper end to engage the spigot or lower end of the pipe or spout lengthabove an aperture in the socket part in a portion thereof offset to givecleanancebetween the inner side of said offset portion and the spigot orpipe part which is toenter the socket, said clearance being sufficientto enable the head of the nail or supporting means, or attachmenthereto, to

lie between the said part and the said spigot or end.

Theinvcntion will now be described with reference to the accompanyingdrawings, in which Figure 1 is a vertical cross section through a pipe.

Figure 2 is a horizontal cross section on line A-A of Figure 1, and

Figure 3 isa modification indicating a different manner of supportingthe pipe or spout using a flexible member for holding the same tothe-spike or the like.

In these drawings the pipe or spout 1 is provided-with a socket 2 intowhich the spigot end of the pipe orspout length above is intended to bean easy fit.

In this socket end a slot 3 or other suitable aperture 4 may be made sothat the pipe or spout may be hung directly from a spike,

nail or hold-fast 5 driven into the wall on the center-line of the pipe.The socket part 2 will be made sufficiently large or have sufficientclearance to allow for the head of the said spike or the like to remainin the space between the inner side of the socket and the outer side ofthe spigot end.

The socket part of the pipe or spout need not necessarily be madecircular in plan but might on the contrary be provided with a projectionor bulge in that part of the socket in which the hole 4 or slot 3 ismade. This bulge or projection might be flattened on its outer side atthe part which rests against the wall so that the said'bulge orprojection serves thetwo-fold purpose of allowing ample clearance forthe spike head or the like and also at the same time serves to steadythe pipe or spout length against the wall.

To steady'the pipe or spout against the:

wall and also to support it away from the wall at a distance which willcause the pipe or spout to hang vertically from its spike or nail theprojections 6, 6, are provided which engage the wall surface 7. Theseprojections steady the pipe owing to the frictional contact with thewall surface. It will be observed that the size and projection of theseparts 6, 6, is considerably less than that of the part 8 (shown indotted lines on Fig- 2) which parts indicate a known form of bracketwhich has sometimes-been cast onto a length of cast iron rain waterpiping so that the pipe may be secured to the wall by an extra spike 9.These known brackets 8 have usually been used in pairs in spite of thefact that it isvery difiicult to drive two spikes evenly'and atdesiredpositions into a masonry wall. In using these known types ofbrackets 8 difliculty has been often experienced owing to the danger ofthe brackets being broken off whilst the spikes are being driven throughthem. Figure 3 shows an, alternative method of supporting the spoutaccording to which the spout is supported by a flexible means such as astiff iron wire which is passed around the pin 11, threaded through thehole 4 in the socket part and attached in any convenient way to thespike 501.. It will be noticed that in this manner of support theclearance needed between the spigot end and the socket is less than thatneeded when the spout is hung directly to a spike-or the like unless thehead of the spike is made very flat indeed.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. An improved rain-water pipe of the spigot and sockettype having an aperture in the socket end, headed supporting meansengaged through said aperture for supporting said part, and saidapertured part being offset from the main part an amount sufficient toallow the headed portion of the supporting means to be positionedfurther from the axis of the pipe than the inner surface of the mainportionof the pipe whereby to per- I smooth while the upper end isenlarged to form a socket, the walls of the socket being provided withan aperture of a size to enable the pipe to be engaged over and hungupon the supporting means, said walls being also arranged to givesuflioient clearance between them and the smooth end of the next lengthof pipe so that the latter can be introduced into the socket andsupported and also posi tioned in spaced relation to the outer end ofthe supporting means.

3. A rain-water pipe according to claim 2, in which the aperture made inthe socket of the same is adapted to support the pipe directly from asupporting means having a flattened head.

4;. A cast iron rain-water pipe accordin to claim 2 having in addition astaying sur ace in the form of a projection provided with a flat portionthereon adapted to engage the Wall to which the pipe is to be fixed forthe purpose of steadying the pipe against the wall, enabling it to hangvertically from its supporting means to prevent, by frictional contactwith the wall any tendency to side movement. 7

In testimony whereof I hereto aflix my signature this 10th day ofAugust, 1928.
